Obviously besides tennis, squash, and racquet ball pros. Somebody below asked about the tennis skills of NFL players and it got me to thinking about the overall question of which sports people are also good or great at tennis.
My vote would be ice hockey players. I know Rob Brindamour is a terrific tennis player. Also baseball infielders. I’ve heard that Mike Schmidt is a great tennis player, although he prefers golf now.
Of course NFL players are great athletes, but I wonder if their size slows them down on a tennis court?
I would say soccer players. A lot of the athletic attributes required are the same. They are extremely fit and not overly muscled, and usually tend to be a similar size to tennis players.
Size can help in tennis, but not when taken to extremes. NFL stars would be too heavily built to be flexible. Sure they can run quickly, but the sudden directional changes in tennis would be tough for them. Not to mention that you need loose muscles to hit a tennis ball hard, not bulging biceps. Basketball players are tall enough to potentially hit good serves, but the height would really be a huge hindrance to movement. There are very few exceptionally tall tennis stars who have had much success, and most have been prone to injuries as well. Although tennis is not a contact sport, it is very hard on joints. Too much height or bulk is usually not a good thing.
